Re: 1988 honda accord dx hatchback won't idle when choke...
Find your cable that goes to your throttle body and look for a screw on a fixed plate, the screw should be touching a cam leaver for the throttle butterfly. if the is no screw it may have rattled out and you may have lost it. Or the idle is done by the computer i in the case you may have a fuilty sensor or computer.

It might just need cleaning. Spray some PB Blaster around the throttle arm where the cable connects to at the base of the carb, and see if that frees up the flaps. And while spraying, fiddle with the throttle linkage.
Look for a screw or nut that turns.Look at the cable that is connected to your accelerator.You can push back on the throttle and hear the engine race.The adjusting screw should be there.A few things to note....Wait until the engine has warmed up and the choke off..check the auto choke is working before you play with the idle...replace the air filter...by increasing the idle the Engine will be running"richer" before you adjust anything I would invest in a complete tune-up.The above info is for all carburator engines only.Good Luck.
1986-1989 Honda Accord with Carburetor have a very bad habit that is little known even by most mechanics but easily fixed at home. The vacuum port on the choke opener that is connected to the intake manifold and both vacuum ports on the fast idle unloader get plugged up with nasty hard carbon almost as hard as metal. When this happens the choke sticks closed and the idle sticks on fast idle when the engine is cold and nobody can figure out why. All you have to do is attach a small drill bit to the end of a flexible socket-driver extension and put it in a variable speed drill that will let you run it real slow and carefully drill out the vacuum ports that are plugged. After they are nice and clean use a vacuum pump tester to make sure the choke opener and fast idle unloader are working before putting it all back together. It's amazing how much better the car runs after cleaning out those ports.
hello first check your idle with the car running foot on brake see were your rpm reading is if your below 500rpm check your label underhood for your curb idle setting second see if theres a adjustment screw you can increase were your gas cable lever rest against your set screw underhood if you feel confident enough remove your iac motor idle air control valve if the bore were the end of the pintle extracts out to close has varnish builup our carbon it will stick creating vacuum leak type senario causing stalling rough idle sometimes even no start conditions good luck
